Patented in England, 04 Jan, 1889; in France, 11 Jun 1889; in Belgium, 15 Jun, 1889; in Italy, 30 Jun, 1889 and in Canada, 08 Nov, 1889.
Claim:
Wood-screws hitherto have been made by a series of operations, which may be specified as follows, omitting the drawing of the metal into wire and beginning with the operation which has specific reference to the making of a screw: first, the cutting from wire of a piece required for a screw; second, the swaging of a rough head upon one end of the piece cut off for a screw by upsetting the metal in a die by means of a machine known as a header or heading-machine, the piece of metal is now called a screw-blank third, the shaving of the entire head thus formed to perfect its form and give it the required size; fourth, the cutting of a slot across the face of the head; fifth, the re-shaving of the head. to remove the burr formed in cutting the slot; sixth, the cutting away of the metal at the opposite end of the piece to reduce it to a point; seventh, the formation of the thread by cutting a spiral groove around a portion of the body of the wire or screw-blank, so-called. The cutting-tool is applied to the blank several times, making repeated cuttings to complete the thread. In these operations about forty per cent. of the metal is cutaway and becomes waste. |
